. My invention relates to units for drainage systems, including systems forwthe disposal of the ellluent water from septic tanks, grease traps etc., the invention `being suitable also for use in draining water from swampyground, after the manner of French drains. l

In the draining of comparatively clear water from septic tanks andthe like, it is frequently conducted through drain `tile to` porous soil or gravel beds, to effect dissipation ofthe eiiluent water intothe soil. Usually the drain tile sections have their ends spaced slightly apart to allow the water to leak between such ends, into the absorption bed, but 'the pipes` are embedded `in the gravelor the porous soil, and there is iniiltration of betweenthe ends of. the tile sections, so that ltrouble is` frequently encountered through clogging of the drain tile. Even where no such infiltration of dirt occurs, there is obstruction to freelow of water through these `spaces betweenthe ends `of the pipes or` tile sections, `because of close proximity of the gravel or `the like in which the drain ti1e,is embedded.

This objection applies alsoto `the draining of` soil or swampy land to remove water therefrom. .One object of 1 my` invention `is to provide a 6 structure of the character referred to, wherein the drain pipes are supported in such manner that they will not become clogged by dirt `or gravel at the `absorption beds, and wherein there is no obstruction to free flow of Water fromthe pipes to the absorption beds. Y

Another object of my invention is to provide` a system of the character referred to wherein I the parts can be made largely from conventional forms of sewer pipe and the like.`

Still another object of my invention is to prol vide a `drainage system with an improved manner for introducing chemicals for treating the liquid .passing therethrough, or for dissolving greasefwhichfmeans may also serveas` a convenient manner for effecting aeration, with supply of oxygen to the eiuent fromsepticvtanks A further object is to provide a means anda method of laying conduits of drain tile or sewer pipes in such manner that danger of tree roots the structureof Fig. 2; Fig`. 6 is a modied view` of one of the drain tilemembers of Fig. 1; Fig.

l 7 is a perspective viewof a modication ofthe drain pipe and shield structure of Fig. 3; Fig. 8 is a side view of the drain pipe of Fig. 7;Fig. 9 showsanother modiiication of the structure of Fig. 1; Fig. 10` shows still another form ofthe invention, in fragmentaryV plan view; Fig. 11 is `anrend view thereof partly in section, andFig.

`12 is a fragmentary perspective view showing three of the units of` Fig. l0 in assembled relation.

Referring first to Figs. 1, 2 and `3, II indicates a sewer or drain line leading from a septic tank or some other source, slightly sloping downward-y ly in the direction indicated by the arrow. This drain line II is `mounted in vertically-spaced rel lation to an absorption bed I2, which may be `of gravel,` broken stone, ,or simply a porous soil.`

Shield members I3 are placed upon the absorptionbed I2 and `may conveniently consist of ordinary sewer pipes split in half lengthwise thereof. Drainpipes I4 are supported within the shield members I3. To this end, the members I3 and` I4, while in aplastic or` green condition, can be pressed together land then red, so that they will, in effect, be fused together at I5, there` by aording vertical support for the drain pipesA `III. Thepipes I4,.whi1e green, canhave onehalf of their hubs cut away, as indicated at I6,

so that thepipes can have better iit and accurate alignment with one another. Also, they have slots or holes Il punched therethrough,'to permit water to flow from the pipes to the absorption bed. l

At least one ofthe shields I3 has a hole cut therein, and a pipe 20 extending upwardly therefrom, the pipe 20 having communcationthrough the shield, with the `space above the lter bed, either directly or through one of the pipes I3. This pipecan serve as a means` `for introducing chemicals, greasey solvents etc. to the lter bed,

and when its `cover 2| is removed, it `can serve entering the conduit through holes `or joint l l spaces is reduced.

Some of the formswhich myinvention may take are shown in the accompanying drawings wherein Figure 1 is a longitudinal sectional view through an absorption bed, with my invention n incorporated therewith; Fig. 2 is an enlarged view taken on` the linen-II of Fig. 1; Fig. 3`

as a Ventilating pipe or for `aeration of the filter bed to admit oxygen of the atmosphere to the waste material in the bed.

It will be understood that in the case `of the abovefdescribed structure, as well as certain `of the otheriorms herein shown, the parts may be made of other materials such as concreteor metal. Also, unperforated drain pipes can be used,

on stools or chairs I8 at intervals, in verticallyspaced relation to the absorption bed l2.

IAs shown in Fig. 6, the pipes I4 may be per- 3 l5 will discharge laterally in one direction and the iorated on only one side, in which case one pipe succeeding pipe laterally inthe, opposite direction, the holes Il in the s'ucedir'ig pipe "being in the opposite side thereof.

While the joints of sewer pipesv are usually cemented, this is not always done, and furthermore, cemented joints sometimes break, through settling or otherwise. If the sewer pipes are supported above the bottom of' the sewer trench and shields placed to exclude dirt from the space below them, the tendrils of `tree roots will not ordinarily come into Contact with them.
